Hi There are a few posts about confirmation emails but this one seems the closest the the issue I'm getting with a new Power Pages site I'm working on.
I'm not having a great time trying to get user authentication to work so tried the user register approach to see what happens.
Prompt on the site.

This triggers an email to IT support to approve the request.
On approval this add my record to the Contact table and on return the site prompts me to update my contact information and confirm my email.

On clicking confirm email I go to this screen

Over 2 hours later I haven't received an email.
However, the email details are recorded against my record in the Contacts table.

Any idea how to resolve the blockage?
Thanks in advance.
